2011-09-09build: fix missing trace dep on GENERATED_HEADERSMichael Roth1-0/+2
fc764105 added an include for qemu-common.h to trace/control.h, which made all users of this header file dependent on GENERATED_HEADERS. Since it's used by pretty much all the trace backends now, make trace-obj-y dependent on GENERATED_HEADERS.

2011-09-01trace: [stderr] add support for dynamically enabling/disabling eventsLluís1-0/+2
Uses the generic interface provided in "trace/control.h" in order to provide a programmatic interface as well as command line and monitor controls. Signed-off-by: Fabien Chouteau <chouteau@adacore.com> Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
2011-09-01trace: add "-trace events" argument to control initial stateLluís1-0/+2
The "-trace events" argument can be used to provide a file with a list of trace event names that will be enabled prior to starting execution, thus providing early tracing. This saves the user from manually toggling event states through the monitor interface or whichever backend-specific interface. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>

2011-08-21guest agent: remove uneeded dependenciesMichael Roth1-0/+9
This patch tries to cull any uneeded library dependencies from the guest agent to improve portability across various distros. We do so by being as explicit as possible about in-tree dependencies rather than relying on existing *-obj-y targets, and by manually setting LIBS for the qemu-ga target to avoid pulling in LIBS_TOOLS libraries discovered by configure.

2011-08-04usb: use iovecs in USBPacketGerd Hoffmann1-0/+1
Zap data pointer from USBPacket, add a QEMUIOVector instead. Add a bunch of helper functions to manage USBPacket data. Switch over users to the new interface. Note that USBPacket->len was used for two purposes: First to pass in the buffer size and second to return the number of transfered bytes or the status code on async transfers. There is a new result variable for the latter. A new status code was added to catch uninitialized result. Nobody creates iovecs with more than one element (yet). Some users are (temporarely) limited to iovecs with a single element to keep the patch size as small as possible. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Add new block driver callbacks bdrv_co_readv/writev, which work on a QEMUIOVector like bdrv_aio_*, but don't need a callback. The function may only be called inside a coroutine, so a block driver implementing this interface can yield instead of blocking during I/O. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-08-01coroutine: implement coroutines using gthreadAneesh Kumar K.V1-0/+4
On platforms that don't support makecontext(3) use gthread based coroutine implementation. Darwin has makecontext(3) but getcontext(3) is stubbed out to return ENOTSUP. Andreas Färber <andreas.faerber@web.de> debugged this and contributed the ./configure test which solves the issue for Darwin/ppc64 (and ppc) v10.5. [Original patch by Aneesh, made consistent with coroutine-ucontext.c and switched to GStaticPrivate by Stefan. Tested on Linux and OpenBSD.] Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-08-01coroutine: introduce coroutinesKevin Wolf1-0/+7
Asynchronous code is becoming very complex. At the same time synchronous code is growing because it is convenient to write. Sometimes duplicate code paths are even added, one synchronous and the other asynchronous. This patch introduces coroutines which allow code that looks synchronous but is asynchronous under the covers. A coroutine has its own stack and is therefore able to preserve state across blocking operations, which traditionally require callback functions and manual marshalling of parameters. Creating and starting a coroutine is easy: coroutine = qemu_coroutine_create(my_coroutine); qemu_coroutine_enter(coroutine, my_data); The coroutine then executes until it returns or yields: void coroutine_fn my_coroutine(void *opaque) { MyData *my_data = opaque; /* do some work */ qemu_coroutine_yield(); /* do some more work */ } Yielding switches control back to the caller of qemu_coroutine_enter(). This is typically used to switch back to the main thread's event loop after issuing an asynchronous I/O request. The request callback will then invoke qemu_coroutine_enter() once more to switch back to the coroutine. Note that if coroutines are used only from threads which hold the global mutex they will never execute concurrently. This makes programming with coroutines easier than with threads. Race conditions cannot occur since only one coroutine may be active at any time. Other coroutines can only run across yield. This coroutines implementation is based on the gtk-vnc implementation written by Anthony Liguori <anthony@codemonkey.ws> but it has been significantly rewritten by Kevin Wolf <kwolf@redhat.com> to use setjmp()/longjmp() instead of the more expensive swapcontext() and by Paolo Bonzini <pbonzini@redhat.com> for Windows Fibers support.

2011-07-22USB: add usb network redirection supportHans de Goede1-0/+1
This patch adds support for a usb-redir device, which takes a chardev as a communication channel to an actual usbdevice using the usbredir protocol. Compiling the usb-redir device requires usbredir-0.3 to be installed for the usbredir protocol parser, usbredir-0.3 also contains a server for redirecting usb traffic from an actual usb device. You can get the 0.3 release of usbredir here: http://people.fedoraproject.org/~jwrdegoede/usbredir-0.3.tar.bz2 (getting a more formal site for it is a WIP) Example usage: 1) Start usbredirserver for a usb device: sudo usbredirserver 045e:0772 2) Start qemu with usb2 support + a chardev talking to usbredirserver + a usb-redir device using this chardev: qemu ... \ -readconfig docs/ich9-ehci-uhci.cfg \ -chardev socket,id=usbredirchardev,host=localhost,port=4000 \ -device usb-redir,chardev=usbredirchardev,id=usbredirdev Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-07-21qapi: add QMP dispatch functionsMichael Roth1-1/+1
Given an object recieved via QMP, this code uses the dispatch table provided by qmp_registry.c to call the corresponding marshalling/dispatch function and format return values/errors for delivery to the QMP. Currently only synchronous QMP functions are supported, but this will also be used for async QMP functions and QMP guest proxy dispatch as well.

2011-07-21qapi: add QMP output visitorMichael Roth1-1/+1
Type of Visiter class that serves as the inverse of the input visitor: it takes a series of native C types and uses their values to construct a corresponding QObject.

2011-07-21Add hard build dependency on glibAnthony Liguori1-0/+1
GLib is an extremely common library that has a portable thread implementation along with tons of other goodies. GLib and GObject have a fantastic amount of infrastructure we can leverage in QEMU including an object oriented programming infrastructure. Short term, it has a very nice thread pool implementation that we could leverage in something like virtio-9p. It also has a test harness implementation that this series will use.

2011-06-14libcacard: add libcacard.la targetAlon Levy1-0/+8
No flag to configure is required. Instead, added a libcacard.la target that is not built by default, only when requested explicitly via: mkdir build cd build ../configure make libcacard.la make install-libcacard Uses libtool to do actual linking of object files and shared library, and installing. Tested only under linux, but supposed to work on other systems as well. If libtool isn't found you get a message complaining about that, only at build time (since it is not a default target I did not add a message at configure time). New build artifacts: .libs subdirectories (at <buildroot> and <buildroot>/libcacard) *.lo files (at same locations as the respective o files) Added %.lo : %.c rule that uses libtool. Updated clean rule to clean up those artifacts. Added specific rule to call dtrace with libtool wrapper (note that because of a current upstream dtrace bug fixed by systemtap b1568fd85 commit the -fPIC flag isn't actually passed on. still current dtrace+libtool produced object links fine). If libtool is missing any of the following targets will complain and exit 1: any subdir: *.lo root and libcacard: libcacard.la, libcacard-instsall Tested to link and load with all tracing backends.

Commit 353ac78d495ef976242abd868f68d78420861c2c moved the files without fixing the include paths. It used a modified CFLAGS to add hw to the include search path, but this breaks builds where the user wants to set special CFLAGS. Long include paths also increase compilation time.
